1.Flu Fallout: Information Production Constraints and Corporate Disclosure（JAR）

Using influenza epidemic data, we examine how constraints on corporate information production affect disclosure policies. We find that firms in areas with higher flu activity are less likely to issue short-run earnings forecasts and more likely to issue long-run earnings forecasts. These results are more pronounced when the information production process is more complex, when managers face a greater reputational loss for issuing low-quality short-run forecasts, and when firms’ costs of switching the forecast horizon are lower. Further analysis implies that the effect of flu activity on these forecast issuance decisions is not driven by firm performance or information uncertainty. Our results suggest that managers do not simply avoid issuing forecasts in response to information production constraints. Instead, they shift the forecast horizon from short-run to long-run, appearing to balance the costs of issuing low-quality forecasts with those of not issuing forecasts at all.

2.The Real Effects of Modern Information Technologies: Evidence from the EDGAR Implementation（JAR）

Using the implementation of the Electronic Data Gathering, Analysis, and Retrieval (EDGAR) system from 1993 to 1996 as a shock to information dissemination technologies, we examine how a significant reduction in disclosure processing costs affects the real economy. We find that the EDGAR implementation leads to an increase in corporate investment and that this effect is concentrated in value firms. We provide evidence that improved equity financing and enhanced managerial incentives are likely the underlying mechanisms. Specifically, the EDGAR implementation leads to an increase in a firm's stock liquidity, a decrease in the cost of equity capital, and an increase in the level of equity financing. Consistent with the monitoring effect of broad information dissemination, the EDGAR implementation leads to an increase in a firm's operating performance. Our findings suggest that it is important to consider information dissemination beyond information production when examining the real effects of corporate disclosures.

3.Reusing Natural Experiments（JF）

After a natural experiment is first used, other researchers often reuse the setting, examining different outcome variables. We use simulations based on real data to illustrate the multiple hypothesis testing problem that arises when researchers reuse natural experiments. We then provide guidance for future inference based on popular empirical settings including difference-in-differences, instrumental variables, and regression discontinuity designs. When we apply our guidance to two extensively studied natural experiments, business combination laws and the Regulation SHO pilot, we find that many results that were statistically significant using single hypothesis testing do not survive corrections for multiple hypothesis testing.

4.Do Digital Technology Firms Earn Excess Profits? Alternative Perspectives（TAR）

Despite regulators’ allegations that digital technology giants misuse their market power to earn abnormal profits, there is a dearth of systematic work on (1) whether digital-tech firms in general, and tech giants in particular, earn excess profits or (2) whether their abnormal profitability, if any, is due to market power. We use the following two alternative measures of economic profitability in addition to accounting rate of return (ARR): internal rate of return (IRR), which equates current investments to their long-term payback, and return on invested capital (ROIC), whose numerator (profits) and denominator (invested capital) are adjusted for capitalized intangibles. Inferences based on IRRs differ from those based on ARRs and ROICs. IRRs show that the digital-tech sector is now the best-performing sector, and its gap between profitability and cost of capital has increased over time. We are unable to separate the contribution of market power and innovation to digital tech’s high IRRs.

5.Do Firms Mimic Industry Leaders’ Accounting? Evidence from Financial Statement Comparability（TAR）

Following management theory on organizational legitimacy, we predict that managers mimic the accounting of industry-leading companies to gain legitimacy. Such demand for legitimacy is expected to be greater for new managers because stakeholders are more uncertain about the managers’ ability. Using a sample of CEO turnovers, we find that a firm increases financial statement comparability with industry leaders after the new CEO assumes office. This relation is stronger when (1) new managers lack executive experience at larger firms, are younger, or belong to an underrepresented group (i.e., are female or nonwhite); (2) networks that facilitate imitation are more intense, such as when firms and peers are located in the same metropolitan statistical area (MSA) and when they share auditors or blockholders; and (3) firms’ operating environments are more volatile. These findings support the idea that CEOs’ demand for legitimacy leads to more comparable accounting.

6.Externalities of Accounting Disclosures: Evidence from the Federal Reserve（TAR）

This study provides the first empirical evidence that the Federal Reserve (the Fed) systematically retrieves micro-level accounting reports to aid its understanding of the state of the macroeconomy. Using unique data identifying its direct access of corporate SEC filings, we show that the Fed tracks firms that are bellwethers and industry leaders, or that can engender systemic risk. The qualitative information in the Fed-accessed periodic reports explains the Fed’s GDP growth forecasts for up to four quarters, after controlling for contemporaneous aggregate earnings and other economic information. However, professional forecasts fail to incorporate such qualitative accounting information. In addition, this qualitative information is reflected in the tone of the ensuing FOMC meeting discussions as well as in Fed forecasts of key macro demand and supply factors. Overall, our evidence suggests important externalities of micro-level accounting reports, especially qualitative disclosures, on the central bank’s macroeconomic forecasts and, by extension, monetary policy.
